gönderme veri Bluetooth Modülü HC-05 aracılığıyla bir Android uygulaması için arduino veri göndermek için çalışıyorlar

Question

Android'e ve ben arduino herhangi okumaları alamadım Arduino kodu:

void setup() { 
    Serial.begin(9600); 

} 

void loop() 
{ 
    char c; 
if(Serial.available()) 
    { 
    c = Serial.read(); 
    Serial.print(c); 
    } 
} 

Android kodudur:

Ben şu anda gördüğünüz ilk sorunun Arduino kodu vardır: Sen olmuyorsun giriş ve çıkış için aynı Seriyi kullandığınız için mesajı Bluetooth üzerinden gönderme. Serial1 kullanarak Arduino Mega kullanıyorsanız bunu düzeltin (TX1 ve RX1'i kullanma). Bir Mega kullanmıyorsanız, yeni bir özel Seri oluşturmanıza izin veren SerialSoftware kitaplığını kullanmayı düşünmelisiniz.

Arduino kurulumunuzu, onu nasıl kurduğunuzu görmek için görmek güzel olurdu.
